Defense City From Meteor Attack

Welcome to join the city defense against meteor attack.
Your mission is to protect your city against meteor attack. Plenty meteors fall down on your city, you have to destroy them by launching missiles! If they hit your city, the buildings will be destroyed. If all the buildings are destroyed, then, the game is over. As the level increases, the attacking meteors will become more and faster. Try to survive as long as possible and shoot meteors as many as possilbe!
The launched missile will be sent to the target where you tap on the screen. And then, it will explode. If the attacking meteor falls down into the exploding area, then, it will be intercepted successfully. So, the game tips are that you’d better launch missiles to the place where the attacking meteor is heading.
Protect your city. Good luck.
